Cranial nerves that have a motor function tend to be bilaterally innervated. In other words, the right accessory nerve (XI) receives input from both the right and the left motor cortex. The same goes for the left accessory nerve.
This is a handy advantage in strokes, since upper motor neurone lesions must therefore be bilateral in order to cause a deficit.
The one major exception to this rule is the facial nerve (VII). Only the forehead muscles are bilaterally innervated, so even a unilateral upper motor neurone lesion can cause mouth drooping, etc. However, this can still often be differentiated from a lower motor neurone lesion, which will not spare the forehead.

What is bilateral legs mean?
Bilateral in medical terminology basically means "both", so bilateral feet would be both feet. The "bi" means two. Unilateral would mean one, such as unilateral hand pain on the left or right, but not both hands. Hope this was helpful! RG
Are nerves and nerons the same thing?
You may mean 'are nerves and neurons the same?' They are not the same Nerve : Any of the cordlike bundles of fibers made up of neurons through which sensory stimuli and motor impulses pass between the brain or other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body. Nerves form a network of pathways for conducting information throughout the body. Neuron: Any of the impulse-conducting cells that constitute the brain, spinal column, and nerves, consisting of a nucleated cell body with one or more dendrites and a single axon. Also called nerve cell. (American heritage Dictionary)

What does grossly neurovascularly intact distally mean?

What does scierosis mean?
"Sclerosis" refers to the hardening or thickening of tissues or organs. It can occur as a result of various conditions, such as multiple sclerosis, a disease that causes damage to the protective covering of nerves in the brain and spinal cord.
What does carnial nerves mean?
Cranial nerves are a group of 12 pairs of nerves that arise directly from the brain and brainstem, rather than from the spinal cord. These nerves are responsible for providing motor and sensory innervation to structures of the head and neck, as well as certain viscera. They are important for functions like facial expression, eye movement, taste sensation, and hearing.
What does bilateral neural foramina mean?
The holes on the left and right side of the spinal cord that the nerves are protected in from top of spine to lower spine.
What are the 7th and 8th cranial nerves appear grossly normal mean?
When the 7th (facial) and 8th (vestibulocochlear) cranial nerves appear grossly normal, it indicates that there are no visible abnormalities or lesions affecting these nerves upon examination. This suggests that the nerves are intact and functioning properly, which is important for facial movement, sensation, and hearing/balance. Such findings can help rule out certain neurological conditions or injuries. However, further testing may still be necessary to assess their function more thoroughly.
What is a bilateral brow ptosis?
I wonder if you mean (eye lid droping) not brow search in google for images causes of ptosis are: 1-Horner's syndrome 2-3rd cranial nerve damage but they above causes are causing unilateral ptosis bilateral ptosis can be caused by general muscle weakness, like in myasthenia gravis
What does Olympus mean in medical terms?
The most common use of "olympus" in medical terms is the mnemonic used to remember the names of the cranial nerves. The mnemonic is, "On old Olympus' towering top, a Finn and German viewed some hops." Olympus represents cranial nerve III, the oculomotor nerve.

What does bilateral mean in science?
Bilateral means on both sides. Lateral pertains to the side of something.
What does early narrowing of the bilateral intervertebral foramina mean?
Early narrowing of the bilateral intervertebral foramina refers to the initial signs of reduced space between the vertebrae where spinal nerves exit the spinal column. This condition can result from factors like disc degeneration, bone spurs, or other changes in the spine. Such narrowing may lead to nerve compression, potentially causing pain, numbness, or weakness in the areas served by the affected nerves. Early intervention can help manage symptoms and prevent further complications.
What is bilateral uncovertebral hypertrophy and mild bilateral foraminal narrowing in c5-c6 mean?
Bilateral uncovertebral hypertrophy at the C5-C6 level refers to an enlargement of the uncovertebral joints, which are located on the sides of the cervical vertebrae, potentially leading to nerve compression. Mild bilateral foraminal narrowing indicates that the openings (foramina) through which spinal nerves exit the vertebrae are slightly constricted on both sides. This condition can result in neck pain or radiating symptoms due to nerve irritation. Overall, these findings suggest degenerative changes in the cervical spine that may warrant monitoring or treatment depending on symptoms.
What does you suffer from the nerves mean?
Suffering form nerves usually means you are stressed
Does cranial mean superior?
No, cranial refers to the direction towards the head, while superior refers to a higher position in the body. While they are related concepts, they are not synonymous.
